Merge branch 'sctp-clean-up-sctp_connect-function'

Xin Long says:

====================
sctp: clean up __sctp_connect function

This patchset is to factor out some common code for
sctp_sendmsg_new_asoc() and __sctp_connect() into 2
new functioins.

v1->v2:
  - add the patch 1/5 to avoid a slab-out-of-bounds warning.
  - add some code comment for the check change in patch 2/5.
  - remove unused 'addrcnt' as Marcelo noticed in patch 3/5.
